YOU WILL HAVE TO INCREASE THE IDLE RPM.
Has it had a chance to relearn its idle since disconnecting the battery cables ?
i would call a dealer 1st. 2nd does
you probobly just need to change your spark plugs and wires.
i think it could be your FUEL PRESSURE REGULATOR. ours did that too
if recently did tune up check firing order for misfire on wires..check oxygen sensors or throttle position sensor..also possibly idle air control sensor
you have a short in your alarm system. this will cause your engine to idle ruff and cut off, or, not start at all.
Check for codes in OBD. I have seen a bad engine coolant sensor do that.

the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved. the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved.
